The scraper is installed between the front and rear axles of the machine and can be raised and lowered, tilted, rotated and extended. It is flexible and accurate in movement, easy to operate, and can level the ground with high precision. It is suitable for building roadbeds and pavements, building slopes, and digging ditches. It can also mix road mixtures, remove snow, push bulk materials, and maintain dirt and gravel roads.

[0003] For example, a Chinese patent with publication number CN217679330U discloses a road grader with auxiliary cleaning, including a grader cab, wherein the front end of the grader cab is fixedly connected to two fixing rods, the opposite ends of the two fixing rods are rotatably connected to connecting rods, and the opposite ends of the two connecting rods are jointly rotatably installed with a blade part, and a blade telescopic mechanism is fixedly installed inside the blade part, and the rear end of the grader cab is fixedly connected to a fixing frame, and a slide groove is provided at the rear end of the fixing frame, and a cleaning mechanism is slidably installed in the slide groove, and two mounting platforms are fixedly connected to the lower part of the rear end of the grader cab, and sliding holes are provided at the upper ends of the two mounting platforms. The utility model is provided with a cleaning mechanism, which is conducive to cleaning the rear dust when the grader is working and ensuring a clear working field. The blade telescopic mechanism is provided, which is conducive to making the blade actively adapt to the leveling area and improving the functionality of the grader.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: after long-term use, the two cleaning brushes will be worn to a certain extent, which will lead to poor cleaning effect, but the device is not convenient for replacing the two cleaning brushes, and when the two cleaning brushes are cleaning, when the dust on the road surface is relatively dry, the two cleaning brushes will sweep up the dust on the road surface, which will pollute the surrounding air. In view of this, we propose a road grader that can assist in cleaning. Utility Model Content

[0006] The purpose of the utility model is to provide a road grader capable of assisting cleaning, so as to solve the problems raised in the above-mentioned background technology.

[0007] In view of this, the utility model provides a road grader capable of assisting cleaning, comprising a grader cab, and also comprising:

[0008] An L-shaped plate, wherein the L-shaped plate is fixedly mounted on the rear side of the cab of the grader, a water tank is fixedly mounted on the L-shaped plate, a fixing frame is fixedly mounted on one side of the L-shaped plate, a connecting rod is slidably mounted in the fixing frame, L-shaped rods are fixedly mounted on both sides of the connecting rod, a limiting groove and a rectangular groove are provided in the L-shaped rod, the limiting groove is located at the top of the rectangular groove, a cleaning brush is arranged at the bottom of the L-shaped rod, a T-shaped rod is fixedly mounted on the top of the cleaning brush, the upper end of the T-shaped rod passes through the rectangular groove and extends into the limiting groove, a threaded rod 2 is installed on the inner thread of the T-shaped rod, and the top end of the threaded rod 2 passes through the top of the limiting groove and extends to the outside, a U-shaped tube is fixedly mounted on one end of the connecting rod, and a plurality of spray heads are fixedly mounted on the bottom of the U-shaped tube;

[0009] A driving assembly, the driving assembly is located in the fixing frame and is used to drive the connecting rod to move;

[0010] A water supply assembly is located in the water tank and is used to transport water into the U-shaped tube.

[0011] The two cleaning brushes are first placed on the ground and located directly below the two rectangular grooves, respectively, and the upper ends of the T-shaped rods are aligned with the positions of the rectangular grooves. Subsequently, the driving assembly is provided to drive the connecting rod to move downward, and at the same time, the connecting rod will drive the two L-shaped rods and the U-shaped tube to move downward. During the displacement, the upper ends of the T-shaped rods will slowly enter the rectangular grooves. At this time, the L-shaped rods continue to move downward until the upper ends of the T-shaped rods enter the limiting grooves and contact the tops of the limiting grooves. Subsequently, the cleaning brushes are rotated forward to drive the T-shaped rods to rotate forward. When the upper ends of the T-shaped rods rotate 90° in the limiting grooves and cannot rotate any further, the staff manually rotates the handle on the threaded rod second and drives the threaded rod second to rotate. Under the action of the thread, the threaded rod second will move downward until the lower ends of the threaded rod second enter the upper ends of the T-shaped rods, thereby limiting the T-shaped rods and preventing the T-shaped rods from rotating. At this time, the two cleaning brushes are installed.

[0012] Then, the whole device is started, and at the same time, the water supply component is started, so that the water supply component can transport the water in the water tank to the U-shaped tube. Under the action of water pressure, the water in the U-shaped tube will be sprayed out from several spray heads. At this time, the cleaning brush automatically rotates to clean the dust at the rear end. During the cleaning process, the water sprayed from the spray head can play a role in dust reduction, which can prevent a large amount of dust from floating;

[0013] When the two cleaning brushes need to be disassembled and replaced after long-term use, the staff manually turns the handles on the two threaded rods and drives the corresponding threaded rod to rotate. Under the action of the thread, the threaded rod will rotate and move upward until the threaded rod is completely moved out of the T-shaped rod. Then, the cleaning brush is rotated in the opposite direction to drive the T-shaped rod to rotate 90° in the opposite direction, so that the upper end of the T-shaped rod is aligned with the rectangular groove again. Then, the driving assembly is used again to drive the connecting rod to move upward. At the same time, the connecting rod will drive the two L-shaped rods and the U-shaped tube to move upward. During the displacement process, the upper end of the T-shaped rod will slowly move out of the limit groove until the T-shaped rod is completely moved out of the limit groove and the rectangular groove. At this time, the L-shaped rod will be released from the limit and the cleaning brush will be removed.

[0014] In the above technical solution, further, the driving component includes:

[0015] A threaded rod is rotatably mounted in a fixed frame, one end of the threaded rod passes through a connecting rod, a motor is fixedly mounted on the top of the fixed frame, and an output shaft of the motor passes through the top of the fixed frame and is coaxially connected to the threaded rod.

[0016] In this technical solution, the motor causes the output shaft of the motor to drive the threaded rod 1 to rotate forward. Under the action of the thread, the threaded rod 1 will drive the connecting rod to move downward. At the same time, the connecting rod will drive the two L-shaped rods and the U-shaped tube to move downward.

[0017] In the above technical solution, further, the connecting rod is threadedly connected to the threaded rod, and the output shaft of the motor is rotatably connected to the top of the fixing frame.

[0018] In this technical solution, under the action of the thread, it is ensured that the threaded rod can drive the connecting rod to move when it rotates, thereby ensuring that the motor can operate normally.

[0019] In the above technical solution, further, the water supply component includes:

[0020] A water pump is fixedly installed at the bottom of the inner cavity of the water tank, the water outlet of the water pump passes through one side of the inner wall of the water tank and extends to the outside, a water pipe is fixedly installed at the water outlet of the water pump, and one end of the water pipe is fixed to and communicated with the U-shaped pipe.

[0021] In this technical solution, the water pump is started to extract water from the water tank. Then, the water pump will transport the water to the water pipe. The water in the water pipe will then enter the U-shaped tube. Under the action of water pressure, the water in the U-shaped tube will be sprayed out from several spray heads.

[0022] In the above technical solution, further, the T-shaped rod is movably connected to the rectangular groove, and the upper end of the T-shaped rod is rotatably connected to the limiting groove.

[0023] In the technical solution, it is ensured that the T-shaped rod can move in the rectangular groove; it is ensured that the upper end of the T-shaped rod can rotate in the limiting groove.

[0024] In the above technical solution, further, the threaded rod 2 is threadedly connected to the L-shaped rod, and the plurality of spray heads are connected to the U-shaped tube.

[0025] In this technical solution, under the action of the thread, the second threaded rod can drive the L-shaped rod to move when it rotates, ensuring that the water in the U-shaped tube can be sprayed out from the plurality of spray heads.

[0026] In the above technical solution, further, a mounting plate is fixedly installed on one side of the L-shaped plate and on both sides of the fixing frame, and the mounting plate is located on the L-shaped rod, the L-shaped rod is slidably connected to the mounting plate, and a sealing plug is plugged into the water inlet of the water tank.

[0027] In this technical solution,

[0028] The beneficial effects of the utility model are:

[0029] 1. The road grader with auxiliary cleaning function ensures that the two cleaning brushes can be removed from the corresponding L-shaped rods through the cooperation between the T-shaped rod, the limit groove, the rectangular groove and the threaded rod, so that they can be replaced, thereby avoiding the situation where the two cleaning brushes are worn out due to long-term use, resulting in a poor cleaning effect.

[0030] 2. The auxiliary cleaning road grader can ensure dust reduction of the dust generated by the two cleaning brushes during cleaning through the cooperation between the L-shaped plate, water tank, sealing plug, U-shaped pipe, spray head and water supply components to avoid affecting the surrounding air.

[0074] It is worth noting that the water pipe 14 is a hose and has a sufficient length. When the U-shaped tube 8 is displaced, the water pipe 14 will not be tight or folded, and will not hinder the displacement of the U-shaped tube 8.

[0075] It is worth noting that when the connecting rod 10 contacts the bottom of the inner cavity of the fixing frame 12, the two cleaning brushes 11 are located below the several moving wheels at the bottom of the grader cab 1. At the same time, the structure and principle of the cleaning brush 11 of this embodiment are prior arts. For details, please refer to the comparative document (publication number CN217679330U, patent name is a road grader with auxiliary cleaning), which will not be repeated here.

[0076] Working principle: when installing the two cleaning brushes 11, first place the two cleaning brushes 11 on the ground and respectively under the two rectangular grooves 19, and align the upper end of the T-shaped rod 17 with the position of the rectangular groove 19. Then, the staff starts the motor 5 so that the output shaft of the motor 5 drives the threaded rod 6 to rotate forward. Under the action of the thread, the threaded rod 6 will drive the connecting rod 10 to move downward. At the same time, the connecting rod 10 will drive the two L-shaped rods 7 and the U-shaped tube 8 to move downward. During the displacement process, the upper end of the T-shaped rod 17 will slowly enter the rectangular groove 19. At this time, the L-shaped rod 7 continues to move downward until the connecting rod 10 moves downward. Until the upper end of the T-shaped rod 17 enters the limiting groove 18 and contacts the top of the limiting groove 18, then, the cleaning brush 11 is rotated forwardly, so that the cleaning brush 11 drives the T-shaped rod 17 to rotate forwardly. When the upper end of the T-shaped rod 17 rotates 90° in the limiting groove 18 and cannot rotate any further, the staff manually rotates the handle on the threaded rod 15 to drive the threaded rod 15 to rotate. Under the action of the thread, the threaded rod 15 will move downward until the lower end of the threaded rod 15 enters the upper end of the T-shaped rod 17, so that the T-shaped rod 17 can be limited to prevent the T-shaped rod 17 from rotating. At this time, the two cleaning brushes 11 are installed.

[0077] Then, the whole device is started, and at the same time, the water pump 13 is started to extract the water in the water tank 3. Then, the water pump 13 will transport the water to the water pipe 14. The water in the water pipe 14 will enter the U-shaped tube 8. Under the action of water pressure, the water in the U-shaped tube 8 will be sprayed out from the plurality of spray heads 9. At this time, the cleaning brush 11 automatically rotates to clean the dust at the rear end. During the cleaning process, the water sprayed from the spray head 9 can play a role in dust reduction, which can prevent a large amount of dust from floating.

[0078] When the two cleaning brushes 11 need to be disassembled and replaced after long-term use, the staff member manually rotates the handles on the two threaded rods 15 and drives the corresponding threaded rods 15 to rotate. Under the action of the thread, the threaded rod 15 will rotate and move upward until the threaded rod 15 is completely moved out of the T-shaped rod 17. Then, the cleaning brush 11 is rotated in the opposite direction, so that the cleaning brush 11 drives the T-shaped rod 17 to rotate 90° in the opposite direction, so that the upper end of the T-shaped rod 17 is aligned with the rectangular groove 19 again. Then, the staff member starts the motor 5 again, so that the output shaft of the motor 5 drives the threaded rod 16 to rotate in the opposite direction. Under the action of the thread, the threaded rod 16 will drive the connecting rod 10 to move upward. At the same time, the connecting rod 10 will drive the two L-shaped rods 7 and the U-shaped tube 8 to move upward. During the displacement process, the upper end of the T-shaped rod 17 will slowly move out of the limiting groove 18 until the T-shaped rod 17 is completely moved out of the limiting groove 18 and the rectangular groove 19. At this time, the L-shaped rod 7 will be released from the limit and the cleaning brush 11 will be disassembled.

[0079] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
